Tutorial: How to create a pattern in Hydroman.

Goal:

Creating your own patterns. In this tutorial we’ll walk through the steps of creating a new drilling pattern.

Steps:

A drilling pattern is basically a Hydroman file with multiple holes in it. There are two different ways to create a pattern.

Starting with an empty pattern file

When starting from an empty pattern file you will only be able to work in one face, this is because for a standard pattern more isn’t required. The isometric viewer is also disabled when creating a pattern file.

In Hydroman the window will now be empty. It is possible to start adding holes for the pattern. The first hole that’s created will be the reference point (0,0) for all the following holes. [Note: Usually the high pressure port (P) is used for reference.]

When the right mouse button is pressed in the empty space, three different options will be shown for adding a hole.

Add [F3] Will let you select a hole from the library to be added to the pattern. This will always add the hole at the reference point (0,0).
Add at Cursor Will also let you select a hole from the library to be added to the pattern, but it will be placed on the coordinates of the cursor.
Create Hole at Cursor Will create a new hole at the coordinates of the cursor

For this tutorial we will use the following filter pattern from Hydac as an example.

We’ll start with creating the inlet port.

The next window will pop-up. In this window you can set the diameter and default depth of the hole.

The default depth isn’t very important as you will most likely change it when creating a manifold. You can also set the coordinates but as this will be used for the reference hole you can leave it at 0,0.

Now move and copy the port 28mm below the inlet port. You can this by using [space] to move the hole and hold [Ctrl] to copy it. The position of the second hole should be (0,-28). Now that both the inlet and outlet port are created we can name the ports.

Also add the remark for the outlet port. We’ve named the inlet port ‘IN’ and outlet port ‘OUT’ so the pattern now looks like the image below.

Now to indicate the size of the O-rings we’ll use hole contours. The outside diameter of the O-rings should be used, in this case it’s the inside diameter plus two times the thickness so: ⌀18 + 2 × 2,5 = ⌀23 mm.

Now the O-rings will be indicated by dashed circles around the ports. Now we will add the threaded holes for mounting the filter. If no bolt size is specified check the size of the hole in the filter and simply make the depth of the thread two times the diameter of the thread. In this case the holes in the filter housing are ⌀13 mm so we’ll use M12 threads with 24 mm depth.

The library will pop up where you can select different components or files.

Now the threaded hole is added from the library to the pattern.

You can now add the other three threaded holes the same way or simply move and copy them with [Space] and holding [Ctrl]. It can be made easy when orthogonal [O] movement and relative values [L] are toggled.

The pattern should now look like the image below.

Now all the holes for the pattern are created we can create a contour for the filter that will be mounted on the drilling pattern. This way you can see where other components around the filter will be able to fit.

A window will pop up where you can add a contour to the pattern, a contour is defined by adding the coordinates of the corners of the contour on the left side. On the right side you can see a preview of the contour. When you only add one value, the contour will be a circle around the reference point with the given diameter. For this filter we will add multiple corner points of the contour. We will start with the top left corner (-40 and 30,5) and go around clockwise.
[Note: It can prove very useful to toggle relative values with the check box in the bottom left]

When finished the contour should look like the following, but you can make it as detailed as you like.

Now the drilling pattern is finished and the contour is created we can add some information to the pattern but it is not required. You can go to ‘Valve List’ [V], and press ‘Add’ to fill out some information.

ave the pattern file to the desired position in the library. Don’t forget to refresh the library afterwards.

Create a pattern from different holes on a manifold

In this example the pattern for the VCM 02-04 (Kracht) is used.

The hole is now in the right position. Here comes the dimensions I earlier changed in place. It is easier to calculate like that where to put the hole.

In this case the A port is the insertion hole on your manifold it can be that it is somewhere else in the list. Then select the hole and move it with the on the of this to the right position. Now you can use Save as… and save the file in the following directory

…\Libraries\Hydroman files . You can make sub folders if you want.

After pressing Save you will see this window

You can add information if you want but is not necessary. Press ok and then cancel to close the other window. Now you have made a PTR file which you can use. The open file you have you can close. You do not have to save it but I always keep those files (somewhere for example on your desktop) in case I have to change something afterwards.

Refresh your library after creating the ptr file otherwise you will not see it.

What we have done is in fact creating a manifold and grouped and save the holes on the manifold.
